PHP Update Simple Xml File

I have searched around a bit and the answer seems to lie in using a DOM object but, after a lot of tinkering, I can't get any of the examples to work and I can't work out what I'm doing wrong. It may be that I'm just using the wrong method.

The xml is really simple..

<?xml version="1.0" encoding="utf-8"?>
<courseinfo>
    <info>Under inspection (decision 13:15)</info>
    <buggies>Yes</buggies>
    <trolleys>No</trolleys>
</courseinfo>

All I want to do is to update and save the child nodes <info>, <buggies> and <trolleys> using form strings.

What is the best way to approach this?

If you need to modify an existing XML document, you can use the SimpleXML Extension to manipulate it using standard PHP object access.

$xml = file_get_contents('foo.xml');

$sxml = simplexml_load_string($xml);

$info = 'New info';
$buggies = 'New buggies';
$trolleys = 'New trolleys';

$sxml->info = $info;
$sxml->buggies = $buggies;
$sxml->trolleys = $trolleys;

file_put_contents('foo.xml', $sxml->asXML());

The most appropriate way is using the PHP native DomDocument class.

$oDoc = new DomDocument('1.0', 'utf-8');

$oInfo = $oDoc->createElement('info', 'under inspection (decision 13:15)');
$oBuggies = $oDoc->createElement('buggies', 'Yes');
$oTrolleys = $oDoc->createElement('trolleys', 'No');

$oCourseinfo = $oDoc->createElement('courseinfo');
$oCourseinfo->appendChild($oInfo);
$oCourseinfo->appendChild($oBuggies);
$oCourseinfo->appendChild($oTrolleys);

$oDoc->appendChild($oCourseinfo);

echo $oDoc->saveXML();

Simple as pie.
